Yeah, it'll probably upscale BDs, and other video, like the PS3 does for 1080p now. They didn't say, but I'm guessing the BD-ROM drive in it is at least 2x speed, that's enough to also do the 4k UHD BD spec that's floating around in draft form right now.

I'd be amazed if any GPU these days could really push a game at 4K consistently. But I've been wrong before, and I'm a little skewed by the complexity of the models I have access to with high end cards.
